I just looked at the manual: they both even go under the same
NWPW
END
input to make matters even more confusing

I f I am correct, the only differentiating thing in the input is
BRILLOUIN_ZONE 
  ZONE_NAME <string name default 'zone_default'> 

  (KVECTOR <real k1 k2 k3 no default> <real weight default (see input description)> 

   ...) 

END

so again, why use one versus the other, e.g. why not always use band?
